A personal account from a CNN health writer highlights how modern marijuana is very different from what many people remember from decades ago.
The writer describes trying cannabis legally in Colorado and experiencing unexpected and intense effects after using a high-potency product from a licensed dispensary.
Medical experts explain that the main psychoactive compound in cannabis, THC has risen dramatically from about 4% in the 1970s to over 20% in many modern products with some concentrates reaching as high as 90%.
Researchers warn that today’s stronger cannabis is linked to higher risks of addiction, mental health issues and cognitive effects, especially with frequent use or use during adolescence. Studies suggest that regular use of high-potency marijuana can increase the risk of dependence and may contribute to conditions like psychosis in vulnerable individuals.
Health experts also highlight broader concerns including impacts on memory, brain development, heart health and increased emergency room visits in heavy users.
Despite legalization in many places, doctors stress that marijuana is not risk-free, especially for young people or those using high-strength products regularly. Occasional, low-dose use carries fewer risks but potency today makes accidental overconsumption more likely.
The article concludes with a warning that many people underestimate how much cannabis has changed and outdated assumptions about its safety can lead to unexpected and sometimes serious health effects.
